Denzel Ward thought he had safety help and let Antonio Brown get behind him in the second quarter of Sunday’s game. Big mistake.

Ben Roethlisberger bought some time moving up into the pocket and hit Brown on a way-too-easy 43-yard touchdown to give Pittsburgh the lead.

Ward was clearly upset that the safety didn’t cover the back end. Whether he blew the assignment or the safety did, it mattered not to the Steelers.
